The number, whose 7% is 42 is:

  • (A) 300
  • (B) 400
  • (C) 500
  • (D) 600
  • Solution: Let’s use the word "7% of" to mean multiplication, and the percent sign will be replaced by a fraction over 100. We’ll use the variable x for the unknown.
  • 7% of x = 42, so: (7/100)x = 42
  • Solving for x: x = (42 × 100) / 7
  • This simplifies to: x = 600
  • So, the correct answer is: (D) 600
